Deep staging also makes your et show up slower. You can run a hundredth or more (Depending on the car, tires, etc) faster than your dial and it doesn't show up. Hard to beat somebody actually breaking out a hundredth, but not showing on the clocks, in a close race.
That is the only complaint I ever heard about it. A fast reacting SS car can't get a green light deep staging. I don't think anybody really cares how long it takes the other car to stage. Some guys, probably just to annoy the other guy, screw around and take a long time to stage shallow.
